Vacuum tube

1. The hardware, or the physical parts of a computer, is one factor that has been constantly changing throughout the development of computers. Two elements of hardware in particular have progressed as generations go on: data transfer and storage. One challenge for computer engineers from the start was deciding how to transfer data through the computer. The first computer, the ENIAC, required 18,000 vacuum tubes to do so, and weighed about 20 tons. Because of its huge size, its power consumption was 150,000 watts (Piguet). Evidently, size and power consumption were major issues from the start. Vacuum tubes were a continuous source of difficulty due to expenses, and the fact that they were constantly burning out. Eventually, the invention of…

The history of computing technology can be organized into four distinct generations, each defined by a distinct transformation in technological innovation. The first generation stretched from 1947-1957, and is identifiable by its use of vacuum tube technology. This generation transitioned into the second generation during the late 1950’s with the use of transistors. Subsequently in the 1960’s the third generation began, classified by its use of integrated circuits. The fourth generation of…

and speed. The second and revolutionary idea was the idea of transistors. A Transistor is a device put inside of a computer or calculator that is used to amplify and switch electronic signals. This basically took a signal from the input device and sent it into the computer and to the output device. This may not seem like that big of a deal but the old technology was much larger, slower and used more energy. The first transistorized computer was in 1953 and completely changed the game. These…

Personal Electronic Devices are a blessing and a curse to society. Some people believe that Personal Electronic Devices will spell the downfall of humanity as we know it and while I don’t personally agree with that statement I can see where people would come to that conclusion from. Personal electronic devices are more addicted to people in today’s society than any other addiction in human history. No other time in history has there been one sole thing that near every human has and uses…

“Twenty two percent of teachers have access to the right level of technology in the classroom.” (PBS, 2011) In this research paper, I will look at technology and the effects on students and teachers; specifically, in a language arts classroom. The problem will be examined over time as technology has changed. In addition, how technology has been integrated into the classroom. There are many facets to technology use in the classroom. The first is how technology is use has changed over time.…

The Impact of Screen Time on Sleep As the Internet develops rapidly in today’s dynamic world, it is extremely hard to imagine how our lives would be without electronic devices. In 2014, an investigation from The National Sleep Foundation found that 89 percent of adults and 75 percent of children have at least one electronic device in their bedroom (Scutti). An child health survey in Australia conducted by the Royal Children’s Hospital Melbourne reveals that almost half of all children (43%) use…

In the article, Watching TV Makes You Smarter, Steven Johnson argues that many of the shows that our population considers unhealthy are actually relatively healthy for our brains. On the other hand, Dana Stevens argues in her essay, Thinking Outside The Idiot Box, that Steven Johnson’s thesis makes absolutely no sense and that television in no way gets our brains thinking or makes us smarter. Johnson starts by explaining what he calls the Sleeper Curve. He does this by comparing older TV shows…

1. List and describe 3 key points made in the video “The Story of Electronics.” • Designed for the dump – products are designed to be hard to repair, breaks easily, and difficult to upgrade. These items led to more devices going to the landfill since it is cheaper to replace them. • Product Takeback – Companies would be responsible for devices and products they produce including their disposal. This could lead to much better designs of the product and devices, which might last longer, have…

I. Have you ever spent too much time watching your favorite TV and lost sleep over it? A. You know you’re supposed to do your homework, but the TV programs have your favorite celebrities so you cannot stop watching them. B. According to the author Demitrios Kalogeropoulos, most recently accessed on December 3, a normal American’s average time of watching television is 4 hours per day. This may not seem like a long time, but it really adds up. C. Too much media may also affect in a…

Children and Media Devices Our media devices have become a valuable part of our everyday lives and the way we communicate; we get text messages for our dentist appointments and e-vites for birthday parties. Mostly this is viewed as a helpful and informative tool for staying in contact with friends and family or receiving news updates and for educational purposes. But, as with most things, there is a limit; how much is too much? My goal is to look specifically at children and the short and long…
